Physics-Informed Machine Learning: When Biomedical Models Need Both Data and Physical Laws

Three PIML frameworks - PINNs, Neural ODEs, Neural Operators - are reshaping biomedical modeling by embedding governing equations into ML loss functions. 10-100x less training data needed, 1000x speedup over FEM for parametric PDEs, and physically-guaranteed plausible predictions. Review from Brown and Yale in Annual Review of Biomedical Engineering.

OCR-Memory: Why Text-Based Agent Memory Loses Evidence - and How Visual Encoding Fixes It

Text memory either burns tokens or loses detail. OCR-Memory from HKU and UNT renders agent trajectories as images, retrieves verbatim evidence through visual anchors with 100% faithfulness, and cuts reasoning tokens by 6.7x - hitting 58.1% on AppWorld and 53.8% Element Accuracy on Mind2Web. Accepted at ACL 2026.
